TRICYCLE.

SPECIFICATION forming part of Letters Patent No. 353,793, dated December '7, 1886.

Application filed May 52:2, 1886. Serial No. 202,983. (No model.) Patented in England August 5, 1884, No. 10,954.

T all whom it may concern:

Be it knownthat we, WALTER JOHN LLOYD and WILLIAM PRIEST, both residing at Harborne, in thecounty of Stafford, England, have invented certain new and useful Improvements in Tricycles, of which the following is a specifieation, reference being had therein to the. accompanying drawings.

This'invention is patented in England, No. 10,954, dated August 5, 1884; complete speciication dated March 27, 1885.

This invention consists of the improvements hereinafter described in the application or adaptation of balance-gearing to the middle of the shaft or principal axis of central-gear tricycles and other velocipedes.

According to this invention the said shaft or axis is made tubular and divided at the middle of its length. In the inner end of one part of the divided shaft is fixed, by brazing or otherwise, asolid cylindrical plug` of about six inches in length. About one-third of the length of the said plug is fixed in thepart of the shaft last referred to, the remaining two thirds protruding from the said part of the shaft. On this protruding end ofthe plug the inner end of the other part of the shalt iits and turns freely. Twotoothed wheels lare fixed, respectively, near the inner ends of the divided shaft. The boss or bush ofthe chainwheel works upon the two ends of the divided shaft, covering and protecting theirjunction. The axis of the third beveled toothed wheel of the balance -gearing works between the gears with the two beveled toothed wheels before mentioned, and is carried by the chainwheel. The outer ends of the two parts of the shaft pass through and work in bearings' carried by the framing ofthe machine, and collars brazed on each of these parts respectively abut against the said bearings and prevent the two parts of the shaft frein separating. By these improvements the tendency in the tricycle or velocipede to a deflection fromarectilinearpatli,which occursintricycles and velocipedes in which balance-gear is applied in the ordinary way` is avoided. Additional strength is given to the shaft or principal axis. When the parts of the balance-gear 5o and shaft are constructed and arranged according to this invention they are not liable to get out orf order.

Figure 1 of the accompanying drawings represents, partly in end elevation and partly in longitudinal section, a portion of accntralgear tricycle, the shaft or axis carrying the central driving or balance gear being coustructed according to our invention. Figs. 2 and 3 represent the two parts of the shaft disconnected.

The saine letters of reference indicate the same parts in the several figures of the drawings.

c b are the two parts of the divided shaft or axis of the tricycle, the part c having fixed on its outer end the traveling wheel c, and the part bhaving fixed on its outerend the traveling wheel d. Both parts, ce b, of the shaft or axis are tubular, and in the inner end of the part c a solid cylindrical plug, e, is fixed, one- 7o third of the said plug being fixed in the part ct and the remaining two-thirds protruding from the said part c of the shaft, as represented. Ve prefer to tix the plug e in its placein thepartc by heatingthe end of thesaid shaft and driving the end of the plug into the slightly-expanded heated end of the shaft; but other ways of fixing the plug in the shaftrnay be used. On the protruding end of the plug e the inner end of the part b of the shaft fits 8o and turns freely.

Near the innerend of the parta of the divided shaft a beveled wheel, f, is fixed, and near the inner end of the other part, b, of the shaft a similar beveled wheel, g, is lixed.

h is the chain wheel,carrying in its interior the usual beveled pinion, i, for gearing with the two beveled wheels on the sections or parts a b, and thereby7 connecting the two shafts together, as is well understood.

7c is the boss or bush of the chain-wheel h, working upon the two ends of the divided shalt and covering and protecting their junetion. (See Fig. 1, where it will be seen that onehalf of the bush 7c is situated on an enlarged 95 part of the plug e, fixed to thehalf-shaft a,and the extreme end of the half-shaft b enters the annular space between the plug @and the other half of the bush lo.)

sides of the bearings p p and preventing the two parts of the shaft from separating, as will be understood from an examination of Fig. 1.

Y Io A third bearing, l1', for the shaft is used near the chain-wheel h.

We prefer to connect the bearings p p r to the frame g of the tricycle by means of screwpins t t, passed through enlargements in the i 5 frame q and iixedby-screw-nuts, the bottoms of the screw-pins t t being formed into forks u, between which the snugs a: w on the tops of the bearings engage and are fixed by cross-pins. The action of the balance-gear applied or 2o adapted'to the shaft according to this invention differs in no essential respect from that of balance-gear of the same kind applied or adapted in the ordinary way, and we therefore do not think it necessary to describe the 25 same.

We claim- 1. In a tricycle, the tubular axle divided in the middle, each axle-section having a bevelwheel secured thereto near the inner end, a'. '5

solid plug entering and secured to one section and entering the otherY section so as to revolve -therein,-and the chain-wheel having its boss covering the junction of the two shafts and bearing a. bevel-wheel engaging the aforementioned bevel-wheels, all in combination substantially as stated.

2. In a tricycle, the tubular axle divided in the middle and having a bevelsecured near the inner end of each section, the solid plug 4secured to one section and entering the other section, the chain-wheel having its hub covering the ends of both axle-sections and bearing the intermediate bevel-wheel, and the framing having abearing near the axle-joint, and other bearings near the outer ends of the axle, all in combination substantial] y as described.

In testimony whereof weaflix our signatures in presence of two witnesses.
